Fwd: Confused deadline reactions

>Hello workflowers,
>in a productive system 4.5B we have a problem with deadline monitoring of
>workflows. For an approval step we use both: Lates Starting Date ( LSD)
>deadline and Latest Ending Date (LED) deadline as well.
>Modelled reactions:
>After LSD:  send a reminder mail to the approver (offset = 4 days)
>After LED:  forward to the director (= boss of the approver) (offset = 9
>days)
>We have about 1000 workflows per day and over a period of one year
>everything worked fine.
>
>Now the system was down for 5 days. After the restart hundreds of workitems
>were forwarded, what is easy to explain: batch report RSWWDHEX was not
>running the last 5 days too.
>But, evidently, report RSWWDHEX now confuses LSD and LED in some (not in
>all)
>cases. It forwards workitems which have just reached the LSD, skipping the
>reminder mail, while LED is stiil 3 days ahead. The  concerned director  is
>not amused by his overflowing inbox...
>The calculation of LSD and LED  is correct, as shown by the workitem
>details.
>So I suspect that SWWDHEX under stress behaves not normally...
>
>Has anyone of you already faced this problem?

>Best regards  and thanks  Uli
